摘　　要：利用试纸法测定镀液中的Ag^(+),可以实现现场测定的简便性。通过试纸变色长度与银浓度之间的线性关系来求得样品中银含量;通过建立试纸长度与银离子浓度线性转换的微信小程序的方法,可直接获得Ag^(+)浓度,该法可测定范围为5~1000μg·mL^(-1)。The test paper method can be used to determine the silver ion in the plating bath,which can realize the convenience of on-site determination.The silver content in the sample can be obtained by the linear relationship between the color change length of the test paper and the silver concentration;the silver concentration can be directly obtained by establishing a wechat small program for the linear conversion between the length of the test paper and the silver concentration.The method can be used in the range of 5~1000μg·mL^(-1).
